Know all by these presents, that the undersigned hereby
constitutes and appoints each of Mark A. Scudder and Heidi
Hornung-Scherr, signing singly, the undersigned's true and
lawful attorney-in-fact to:

	(1)	execute for and on behalf of the undersigned,
in the undersigned's capacity as an officer, director, and/or
ten percent stockholder of Marten Transport, Ltd. (the "Company"),
Forms 3, 4, and 5 in accordance with Section 16(a) of the Securities
Exchange Act of 1934 and the rules thereunder, and all
Schedules 13D and 13G that the undersigned may be required to file
with the U.S. Securities and Exchange Commission;

	(2)	do and perform any and all acts for and on
behalf of the undersigned which may be necessary or desirable
to complete and execute any such Form 3, 4, or 5, or Schedule
13D or 13G, complete and execute any amendment or amendments
thereto, and timely file such form with the United States
Securities and Exchange Commission and any stock exchange
or similar authority; and

	(3)	take any other action of any type whatsoever
in connection with the foregoing which, in the opinion of
such attorney-in-fact, may be of benefit to,in the best
interest of, or legally required by, the undersigned, it being
understood that the documents executed by such attorney-in-fact
on behalf of the undersigned pursuant to this Power of Attorney
shall be in such form and shall contain such terms and conditions
as such attorney-in-fact may approve in such attorney-in-fact's sole
discretion.

	The undersigned hereby grants to each such
attorney-in-fact full power and authority to do and perform
any and every act and thing whatsoever requisite, necessary,
or proper to be done in the exercise of any of the rights and
powers herein granted, as fully to all intents and purposes
as the undersigned might or could do if personally present,
with full power of substitution or revocation, hereby ratifying
and confirming all that such attorney-in-fact, or such
attorney-in-fact's substitute or substitutes, shall lawfully
do or cause to be done by virtue of this Power of Attorney and
the rights and powers herein granted. The undersigned acknowledges
that the foregoing attorneys-in-fact, in serving in
such capacity at the request of the undersigned, are not
assuming, nor is the Company or Scudder Law Firm, P.C., L.L.O.
assuming, any of the undersigned's responsibilities to comply
with any federal, state, or local law or regulation,
contractual, or other obligation.

In consideration of the attorneys-in-fact acting on the
undersigned's behalf pursuant to this Power of Attorney,
the undersigned hereby agrees to indemnify and hold harmless
each attorney-in-fact, each substitute attorney-in-fact, and
each of their respective heirs, executors, legal representatives,
successors, and assigns from and against the entirety of any
 and all losses, claims, causes of action, damages, fines,
defense costs, amounts paid in settlement, liabilities, and
expenses, including reasonable attorneys' fees and expenses
 (collectively, "Losses"), relating to or arising out of the
exercise of this Power of Attorney by any such attorney-in-fact
or substitute attorney-in-fact, and will reimburse each such
indemnified person for all Losses as they are incurred by such
indemnified person in connection with any pending or threatened
claim, action, suit, proceeding, or investigation with which such
indemnified person is or is threatened to be made a party. The
undersigned will not, however, be responsible for any Losses
that are finally determined by a court of competent jurisdiction
to have resulted solely from an attorney-in-fact's or substitute
attorney-in-fact's bad faith or willful
misconduct.

	This Power of Attorney shall remain in full force
and effect until the undersigned is no longer required to file
Forms 3, 4, and 5 or Schedules 13D or 13G with respect to the
undersigned's holdings of and transactions in securities issued
by the Company, unless earlier revoked by the undersigned
in a signed writing delivered to the foregoing attorneys-in-fact.

	IN WITNESS WHEREOF, the undersigned has caused this Power of
Attorney to be executed as of this 8th day of August, 2003.
